      • processElement

        @ProcessElement
        public void processElement​(org.apache.beam.sdk.transforms.DoFn.ProcessContext c)
                            throws Exception
        ProcessElement method for BEAM.
        Parameters:
        c - Process context.
        Throws:
        Exception - Exception on the way.
      • tearDown

        @Teardown
        public void tearDown()
        Teardown, since this logic at the moment should be executed exactly once after consuming the final data element. TODO #274: Use bundles properly in Beam MultinomialLogisticRegression
